Sailboat Diesel Water Systems

Diesel engines run hot because of high compression and therefore need to be cooled. Fortunately, ample cooling is readily available from the water the vessel is sailing in.

Catamaran Maneuvering Mastery

As now learned, Cats can turn inside their own length, they can vector sideways, and using the bulldozer effect you can instantly rotate the Cat to point in any direction, you can do almost anything.

Momentum on a Sailboat

While sailboats are primarily powered by wind, the use of an engine (technically your sailboat engine is “auxiliary power”) is crucial for certain maneuvers and situations. All of this begins with understanding the momentum of a sailboat!

Sailboat Gear and Throttle Controls

Sailboats, and boats in general, use their gears and throttle to control momentum. It’s unlike driving a car in that you have no brake! Instead, you use your forward and reverse gears and throttle to both increase and decrease speed...
